Formula and Step-by-Step

cups × 192g/cup ÷ 28.3495g/oz = ounces
  1. Start with 3 cups of lentils
  2. 1 cup of lentils = 192g
  3. 3 × 192 = 576g
  4. Convert grams to ounces: 576 ÷ 28.3495 = 20.32 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Lentils are dense at 192g per cup. Pour them into the measuring cup and level off without shaking, which settles the beans and increases the weight.

Understanding the Units

What is a Cup?

There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.

What is an Ounce?

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.

Frequently Asked Questions

About 20.32 oz, based on lentils having a density of 192g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 192 (grams per cup for lentils), then divide by 28.3495 to convert grams to ounces. For 3 cups: 3 × 192 = 576g, then 576 ÷ 28.3495 = 20.32 oz.
For the most accurate results, weigh lentils on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.
Weight-per-cup values vary because of differences in how the ingredient is measured (spooned vs scooped), grind size, moisture content, and settling during storage. Our values use standardized measurement methods from established culinary references.
Reverse the conversion: 20.32 oz × 28.3495 = 576g, then 576g ÷ 192 = 3 cups. Or use the Ounces to Cups converter.
